WILL GIVE BRAINLIEST! Given that ℓ1 ∥ ℓ2 and y = 20°, find x. x = °

BabaBlast [244]

X will equal 40.

EXPLANATION: since they’re parallel and these are opposite angles, add them together to equal 180.
x+(20)+3x=180.
add common variables.
4x+20=180
subtract 29 from both sides
4x=160
divide each side by 4 so isolate x
x=40

Joel has a goal to practice his clarinet for 4 1/2 per week. The list below shows the number of hours Joel has a practiced so fa

MrRissso [65]

0.75 hours more is needed to practice to meet his goal

Solution:

Given that,

Goal per week of Joel = $4\frac{1}{2} = \frac{2 \times 4 + 1}{2} = \frac{9}{2}$

From given,

The list below shows the number of hours Joel has a practiced so far for the week

$Monday = 1\frac{1}{2}\ hours = \frac{3}{2}\ hours$

$Wednesday = 1\frac{1}{4}\ hours = \frac{5}{4}\ hours\\\\Thursday = 1\ hour$

How many more hours does he need to practice this week to meet his goal

Find the difference

Hours needed = Goal per week of Joel - (monday + wednesday + thursday)

$Hours\ needed = \frac{9}{2} - (\frac{3}{2} + \frac{5}{4} + 1)\\\\Hours\ needed = 4.5-(1.5+1.25+1)\\\\Hours\ needed = 4.5 - 3.75 = 0.75\\\\Hours\ needed = 0.75 = \frac{3}{4}$

Thus 0.75 hours more is needed to practice to meet his goal
